1. I am a gas intelligent turbine flowmeter used for natural gas. Is there any way to slow down?
It is related. In order to evaluate the impact of gas density changes on small-diameter gas turbine flowmeters, I have provided the results of a noise only density test and some test error curves for a gas turbine flowmeter with a diameter of 10mm (DN10). Before the experiment, a rotary piston standard flowmeter was first used to calibrate the DN10 gas turbine flowmeter with air as the medium at an absolute pressure of 0.2 MPa. This standard flowmeter can be traced back to a foreign laboratory. Then, calibration tests were conducted on the DN10 gas turbine flowmeter using nitrogen (N2), argon (Ar), helium (random He), and air at working pressures of 0.2 MPa and 0.9 MPa, respectively. The experimental results show that when the gas density ρ varies between 0.3Kg/m3 and 1.5Kg/m3, the experimental lift up error curve of the gas turbine flowmeter changes with the change of gas density, and its maximum deviation value is%. When using air medium for testing, the reproducibility error of the test results is better than ± 0.5%, while when using other types of gases, the reproducibility error is about ± 4%. At a working pressure of 0.2 MPa, the experimental error curves using air, argon, and nitrogen are similar in shape and value; Under the same pressure, the experimental error curve of helium gas differs significantly from the error curve of the aforementioned gas. Worth noting; At a working pressure of 0.2 MPa, the density values of air, argon, and nitrogen are about 2-3 kg/m3, while the valence density of helium is about 0.3 kg/m3. In other words, at a working pressure of 0.9MPa, the density of helium gas is approximate
2. Price of gas turbine flowmeter
The price of gas turbine flowmeter varies greatly, with mainstream models ranging from 200 yuan to 10000 yuan. The specific choice depends on measurement needs and installation conditions.
. 1. The distribution of products in different price ranges from basic models to high-end models, with a clear price range: • Low end models (100-800 yuan): Some basic models of Jiangsu Tianxin are only 100 yuan, while the original factory models of the new Tianxin DN series are about 800 yuan, suitable for simple scenarios with low precision requirements • Mid to high end models (2000-8000 yuan): LUXBZ-80 model is 2470 yuan, and Tianxin TBQM-G160-DN80 has a promotional price starting from 2907 yuan, with applicability to normal working conditions • Ten thousand yuan level products: DN100 B-type Tianxiong split gas special model with display+lithium battery is 9860 yuan, and the intelligent digital display vortex street model is 9975 yuan. 2 Analysis of Model and Specification Price Differences: There is a clear price stratification for different specifications of the same brand: in the Tianxin TBQZ series, the 50/300 model is priced at 7650.7 yuan, while the 100A/B/C can be reduced to 230 yuan/unit through bulk procurement. The DN caliber change sub model (50/80/100/150) directly affects the price distribution from 800 yuan to 9860 yuan Optimization points for procurement strategy: TBQZ-100A/B/C tiered pricing mechanism: - Single purchase of 1-9 units at a unit price of 236 yuan ->10 units at a unit price directly reduced by 6 yuan to 230 yuan for Nian Ch
